Pointing all data paths to the files' Dropbox locations.

Some of these files haven't synced on the Dropbox yet, so this won't work until they do (which should happen as soon as zeppelin and macbook have both been connected to the internet for more than a minute or two). I'll probably add an amended commit note when I've confirmed that this works?
Intermediate commit -- cloning gen_ukvar_all into gen_ukvar_all_jjh.

Code is (hopefully clearly) nowhere near ready for running, for a large variety of reasons, but I'm setting some boilerplate down now.
Another "intermediate" commit. Won't work, but mostly there.

Of course I need to bring plot3.jjh into compliance with the functionality desired here, and figure out whether a plot3.jjh_phase is required (holy crap I hope not), and it'd be nice if I didn't have to do the TOTAL refactor to get this stuff going, and there's still the question of syncing the dropbox folders and then testing to see if official_star_counter works... but other than that I hope this makes the cut!
Made path and dependency tweaks to get figure_maker running on mac.

Mainly, more replacing Dropbox paths with computer-independent equivalents, but also I downloaded and installed astrolib.coords (which now always lives inside astrolib) and modified code that used to import "coords" to attempt importing astrolib.coords as coords if regular coords fails.
Reconfiguring paths to be portable/mac-friendly.
Disabled the code that makes glued two-panel plots. Now all are onepanel.

Some minor fixes otherwise: removing parameters that aren't relevant / aren't implemented yet in the jjh function.
Making sure the date_offset is set correctly -- to the Orion startdate.

The code this is cloned from didn't have it because it had plot3.graded_lc(abridged=True) set, which auto-resets the default date_offset to the Orion startdate.

I screwed this up the first time, and amended it to the correct Orion startdate.
